Description

This application claims the benefit of U.S. Provisional application Ser. No. 60/012,822, filed Mar. 5, 1996, and entitled "Metallic Clothing For Carding Segments And Flats."
BACKGROUND OF THE INVENTION
This invention relates generally to metallic clothing with teeth having a double-angled profile, a tapered tip, and a radiused point for use on carding segments and carding flats.
Carding flats and stationary carding segments are generally used in carding machines about the main carding cylinder and produce a carding interface therebetween. Carding flats may also remove trash and non-spinnable fibers during carding. Conventional carding flats often involve the use of flexible wire clothing, which is attached to the flats themselves via adhesive, or some other fastening means. The flexible clothing is produced by providing a flexible substrate, which could be fabric, rubber, plastic, leather, or some combination thereof. The wire clothing is essentially "stapled" through the substrate. After the staples have been inserted through the substrate, the ends of the staples, i.e., the "wires," are subsequently bent at a forward angle and are ground to produce a desired profile.
Production of flexible clothing is relatively labor-intensive and expensive because of the required bending and grinding of the wires after their insertion through the substrate.
Metallic clothing is also known. Metallic clothing does not require a pliable substrate as does flexible clothing, but instead is comprised of a series of wire segments which are stacked side-by-side against each one another in a channel formed in an elongated holder. This holder can be produced of a material such as plastic, or some other material, and is subsequently attached to the flat or carding segment itself via adhesive, clips, or some other fastening means. The advantages of metallic wire clothing are that it is easier to produce and offers longer life. However, in certain applications metallic clothing may tend to not remove trash and non-spinnable fibers as well as does conventional flexible card clothing.
Accordingly, there exists a need for metallic clothing having an improved ability to remove trash and non-spinnable fibers.
SUMMARY OF THE INVENTION
It is, therefore, the principal object of this invention to provide metallic clothing for carding segments and flats which offers both improved manufacturability and durability, and also, an improved ability to remove trash and nonspinnable fibers during carding.
Generally, the present invention includes metallic clothing having metallic wire teeth bent at a doubler angle. The lower portion of each tooth is angled by a first angle with respect to vertical, and the upper portion is angled at a second angle with respect to vertical. The upper portion terminates at the tip, or point, of the tooth. This double-angle tooth profile is angled in the direction opposite to the general direction of travel of fibers being carded. The upper side portion of each tooth is tapered inwardly to the tip, and the rear edge of the upper end of each tooth may be provided with a forward curvature towards the point of the tooth. Additionally, the teeth of the present invention may be of generally taller height than that of conventional metallic clothing teeth.

Accordingly, the drawings, description, and claims are not to be taken as restrictive on the scope of this invention, but are to be understood as broad and general teachings.
Referring now to the drawings in detail, wherein like reference characters represent like elements or features throughout the various views, the metallic clothing of the present invention is indicated generally in the figures by reference character 10.
Turning to FIG. 1, a perspective view of a carding flat or carding segment, generally 12, is illustrated, having metallic clothing, generally 10, provided thereon. Metallic clothing 10 is supported on a holder member, generally 14, and is held against member 14 by elongated clamps, or clips, 18, 20. Each clip 18, 20, includes an upper clamping portion, generally 22, for engaging the edge portions, generally 24, 26, of metallic clothing 10 and a lower clamping portion, generally 28, for engaging lower surfaces, generally 30, of flat 12. Flat 12 also includes an elongated rail portion 32 running substantially the length thereof.
In FIG. 2, a sectional view of the flat 12 illustrated in FIG. 1 is shown. Metallic clothing 10 includes a plurality of segments, generally 34, which are stacked in a side-by-side relationship on upper surface 36 of holder member 14. Each wire segment 34 includes a plurality of teeth, generally 38, which are substantially identical with respect to one another. While wire segments 34 can be stacked in a side-by-side relationship along member 14 in a manner such that teeth 38 on adjacent segments are parallel with one another, (thereby producing uniform rows of teeth along the length of flat 12), it is to be understood that segments 34 can be manufactured such that teeth 38 on adjacent segments 34 are staggered with respect to one another to yield a predetermined pattern of teeth positioned across the width and length of flat 12. These teeth patterns could be any one of a variety of configurations.
Holder member 14 includes upstanding edges 40, 42, respectively, which engage end portions 24, 26, respectively, of wire segment 34. Member 14 is also provided with a recessed portion, generally 44, extending beneath the midportion of segment 34. Base portion 46 of the wire segment 34 rests upon upper surface 36 of member 14 and is also captured by edge portions 40, 42 of member 14.
Clamps 18, 20 include down-turned ends 48 which engage in slots 50 provided adjacent each end 24, 26 of wire segment 34 in order to securely fix wire segments 34 and member 14 with respect to upper surface 52 of the horizontal portion 54 of flat 12.
In FIG. 3A, an enlarged view of segment 34 of metallic clothing 10 is illustrated. Teeth 38 each include a body portion, generally 60, having a lower portion 62 and an upper portion 64. The lower portion 62 extends upwardly from base 46 at an angle a with respect to vertical. Angle a in one preferred embodiment is approximately 15 degrees, although it is to be understood that angle a could be a variety of different angles. Lower portion 62 extends upwardly and terminates into upper portion 64, where an elbow 66 is formed on the backside, generally 68, of tooth 38. Opposite elbow 66 is a corner 70 formed in the leading edge, generally 72, of tooth 38. Upper portion 64 extends at an angle b with respect to vertical. Angle b is preferably approximately equal to angle a, and in one embodiment is thus preferably approximately 15 degrees. However, it is to be understood that angle b could be a variety of different angles. Upper portion 64 terminates at the point 74 of tooth 38.
Upper portion 64 of tooth 38 preferably extends downwardly at an angle c from point 74 with increasing thickness. Angle c is approximately 10 degrees in one preferred embodiment, although angle c could be a variety of different angles.
FIG. 3B illustrates a sectional view of a tooth 38 of metallic clothing 10 constructed in accordance with the present invention. As illustrated in FIG. 3B, upper portion 64 of tooth 38 is provided with a transversely angled upper portion 76 which is angled inwardly to point 74. Angle portion 76 is tapered inwardly at an angle d. Angle d is in one preferred embodiment approximately 10 degrees, although it is to be understood that it could be a variety of different angles.
Adjacent teeth on wire segment 34 include a radiused recess, or valley, 78 therebetween. Valleys 78 could be provided a curved profile having a radius r1, if desired. Radius r1, in one preferred embodiment is approximately 0.254 mm, but could be a variety of different lengths, depending on the particular application of clothing 10. The height h of tooth 38 preferably approximates the height of teeth used on flexible clothing, which is generally taller than that used on conventional metallic clothing.
Turning to FIG. 3C, an enlarged view of the tip portion 74 of tooth 38 is illustrated. Tip portion 74 is provided with a portion 80 curved towards the leading edge 72 of tooth 38. The radius r2 of curved portion 80 in one preferred embodiment is approximately 0.314 mm, but could be a variety of lengths, depending on the desired application of clothing 10.
Metallic clothing 10 is preferably constructed of steel, alloys, or any other suitable material, including material used to construct clothing found on carding cylinders of carding machines.
Angles a through d of clothing 10 could be varied as desired, depending on the fibers being carded, the type of carding machine being used, the flats or carding segment arrangements, etc.
The double-angled profile of metallic clothing 10 is anticipated to provide improved trash and non-spinnable fiber removal during carding, as compared to conventional metallic clothing. It is also anticipated that metallic clothing 10 may be manufactured more expeditiously and will be longer lasting than conventional flexible clothing.
While preferred embodiments of the invention have been described using specific terms, such description is for present illustrative purposes only, and it is to be understood that changes and variations to such embodiments, including but not limited to the substitution of equivalent features or parts, and the reversal of various features thereof, may be practiced by those of ordinary skill in the art without departing from the spirit or scope of the present invention.
